Real estate law, tenancy and cooperative housing and property procedures

Are you purchasing or selling real estate? Do you need advice on exploitation projects? Do you have questions on local plans or building permits? Is any particular form prescribed by law for giving notice to a tenant? What does an agreement on non-enforcement of protected tenancy mean? When is a tenancy forfeited? What does normal maintenance mean? What is the difference between reduced rent and damages? What is the difference between tenancy and leasing? How can a tenancy unit be re-formed as a cooperative housing unit?

ASTRA ADVOKATER often assists clients in purchasing or selling anything from small to large commercial real estate properties. In exploitation projects, we help out with applications for property reallotment and with drafting collaboration and exploitation contracts between parties. We assist in matters regarding shared facilities, easements and utility easements. We also have competence in planning matters and environmental law.

Tenancy is a form of access granting referred to as a right of use. Cooperative housing and leasing are other forms of right of use. ASTRA ADVOKATER provides legal counselling regarding all tenancy, leasing and other right of use relationships within real estate law. For instance, within tenancy law, there are many requirements that landlords often overlook, which can lead to both invalidity and costly consequences. ASTRA ADVOKATER has long experience of drafting tenancy and leasing contracts, non-enforcement of protected tenancy, premise transfers, subletting, damages, renegotiation, extension disputes and mediation in the rent tribunal. We also help out with matters related to cooperative housing, such as re-forming a tenancy unit as a cooperative housing unit.

ASTRA ADVOKATER is a business law firm with broad competence and long-term relationships. Through long-term and close collaborations with our clients, we can provide competent advice for each specific situation.

Thanks to our international network, we can provide counselling in legal, procedural and practical matters, regardless of where an investigation is being performed.
